One hundred nm wide by four mu m long poly(methyl pyrrole) (PMPy) nanowires without and with biomolecule, biotin-quantum dot, were synthesized by electrochemical polymerization of 1-methyl pyrrole with chloride and p-toluene sulfonate dopants in nanochannels between microfabricated gold electrodes. Scanning electron microscopy examination revealed well-confined dendrite free chloride-doped PMPy nanowires with embedded biotin-quantum dot. Current vs. voltage investigation demonstrated ohmic nature of contact for all nanowires. Chloride-doped PMPy nanowires were more conductive than with p-toluene sulfonate doped PMPy nanowires whereas entrapment of biotin-quantum dot increased the conductivity.
